Yes, JG, you most certainly can give up biking for awhile and come back to it. I've done it several times over the course of my adult life, once for several years when I was busy with a demanding job (like you), lived in a not very cycling-friendly area, and was concentrating on other interests for awhile. I later caught the cycling bug again and entered the most cycling-intensive few years of my life, doing five centuries, many more metrics, countless club rides, and a nine-day, self-supported bike tour (565 miles total).
I am currently coming off another long break; this time initiated by fracturing my pelvis in three places in a dog-induced cycling accident (while training for a century), followed six months later by the death of my father in a car accident, which really threw me into a place where I just lost the desire to ride and became too fearful of the road and motorists.
After about a nine month break from riding, I have been taking baby steps towards coming back. I recently discovered mountain biking (no fear of dogs or cars on the road) and love it, and I'm currently planning my first road ride in ten months for this coming weekend. I'm nervous, but hopeful too.
So yes, you can come back! You'll know when it's time. At least you are able to stay active and fit in your work. Cycling will be there waiting patiently when you have the time and interest in returning to it.
